TO ALL, WHOM IT MAYv CONCERN;

Be it known-that'I, F. DAVISON, of Rfichmond,.inv`th e county ofHenricman-dState oth-Virginia, have invented a new and improvedMachinefor MukingNails; and I do lherebydeclare that the followingtis afull, clear, andcxact description thereoi`,\vhich willenablelthosesklle'd inthe art to make and use the saine, referencebeing` had to the accompanying drawings,foimil1g'part ofthisspeci-iieation.'

This invention relates tou 'new and improved machine for making cutnails, and it consists ina peculiar construction and arrangement ofparts, as hereinafter fully shown` andl described, whereby a ve'rysimple and veiieient machine four the purposeis obtained.- *Inv 'the'accompanying sheet of'drawingsi Figure 1 is a side sectional view ofmy'inveiitiom'taken in the line iig. 2.

Figure 2, a transverse vertical section oi` the'sume, taken in the lineyy, iig.. 1. Figure 3, a horizontal section of the same, takenin theline' ze, iig. Similar letters of reference indicate'correspondingparts.o A'represents the frame or stock'of thej machine in which thewerkingparts are placed. B is the driving-- shuft pluced on the upper.part ofV the -frn'me vor stock, and provided with six earns, .C, D, E,F, G,'a.nd H, ea'cln 'oi' which performs a-separate function, as will bepresently shown.

In* the lower part ofV the frame or stock A there is placed a/ rotaryfemalev die, I, which closely resembles u toothed wheel, the spacesbetween' the teeth being the dies,` and corresponding in shape to thedesired taper form of vthe nails-tol be cut. i l i l J is anmle die,which is fitted lvertically in the freine-or. stock A, and worksbetweenthe'teth of: the wheel I, down between the bevelledsnrfnces thereof, asshown iniig. 1, said die J, in its descent, holding the nails in thewheel ordie J'. I I I This male clieJ isi-forced down to its workl bythe cani `C on shait lB, andis'raised by afspriig, K, asshown clearly in-iig. 1.

L represents a cutter, which'cuts the nails from the plate, or, rather,the pieces of which.v the nails are formed. This cutter is fitted in abox, M, v'and'is allowed to slide freely up and .down therein, (see g.3,) and the box M is fitted .in nlrecess or opening in'the stock orframe, which recess or opening is of sufficient capacity to admit of thebox being slightly turned or vibratecl, first in onedirectionand then inthe other, in oder that the cutter L may make oblique cuts, and eut thenailblanks in taper form, in order to give the prepertaper 'form .to i

the nails.

Thecutter L is provided with a cylindrical shankyN, which extends upwardthrough the top of the frame or stock A, and hastwo iianges, O O, on itsupper end, against which the cam D alternately acts and givestheturning-movement to the box`M. v A o The cutter L has u downwardmovementfgi-wn it'by the cam E, n. spring, P, raising the cutter, `(s eeiig,

The box M has an oblong slot, a, made in it for the nail-plate Q to passthrough, the length of the feedmovement of said plate being determinedby a'1ip,i1 on'th'e cutter, shown in figs. l-midZ-Lv R represents atube, through which the 'na-ilplate or har -isfed to the cutter L.

This tube is lined with a. n'on-conducti1ig rnaterialfax, plaster ofParis for instance, t'o retain the heat, and prevent the radiation ofthe samefrorn thenaihplate or ber. i

The tube R is pivoted'in an upright, VS,the lower end of which istted ona shaft, c, on which it :wei-irs" freely.

One or more springs,- d, are attached to the outer' side theupright, S,and-.the cam acts against thev upper part ofthe upright, said cam movingthe upright in one direction, andthe spring or springs moving itini theother direction.- l i l T represents a rising-and falling upright, whichis actuated by the cam G, and hns apa'wl, U, in its lower part, whichengages with the rotary die I, as shownclearly-in iig. 1,-the springbeingkept in'co'ntact `Wtht'lie 'Imaz 2 Within the frame or stockat eachsideV of the die I, at its outer part, there is a curved ledge,f, theouter edges of which are slightly eccentric with the die, (see iig, 1.)v

These curved ledges serve to discharge the nished'nails from themachine, as will be presently explained. v At each side of the frame orstock A there is a heading-die, V, which is actuated by levers W, the`latter being,` operated alternately by the Vcam H. i The dies V arethrown outward by springs Y Y, shown clearly in fig. 2.

The 4operation is as follows: The nail-plate or bar Q is'properly heatedand inserted in the tube R, its end passed through the slot a in the boxM, and brought in contact with the lip b, which serves as a stop. 'l

The cutter L is forced down by the cam E, and a blank cut ofi' from theplate or bar Q with a slightly oblique cut, owing to the obliqueposition of the box M, as previously alluded to.

This nail-blank drops into d'space between the teeth of the die or wheelI, and is carried around underneath the die Jby the elevation of theupright, T, under the action of thecam G,'and when the nail-blank is,

underneath the die J, the latter is forced down by the cam C, so that it`will hold thelnail-blank firmly in the wheel, and the heading-die V,`whcl1 is opposite the thickestend of the nail-blank, is then forcedinward under the action of cam H, and forms the head on said end ofthenail, and against the side ofthe xvheel'I and die J, the nail-blanksbeing of suicient length, somewhat longer than the width 'of the'wheel,te admit of this result. p The die .I thenrises, and the wheel I moved,after a succeeding nail has been cnt an'd dropped into it, as before,the nail-plate or bar Q being fed to the cutter I.' each` time after thelatter has been movedupward by the spring `l?. l y

s The heads of the nails are formed alternatelyat opposite sides of thewheel I,tbe dies V V acting alternately as the nail-blanks are'cut-of`from the plateV or bar Q consecutively with a reverse oblique cut.

l Theffinished nails are discharged from the wheel in consequence of theheads and points catching over the ledgesf, the-eccentrieity'of thelatter, as the wheel rotates, throwing them out from the wheel;

I would remark that Ido not confine myself to the precise position ofthe parts -hercin shown and described;

i as, for instance, they may be placed so that the nail-plate or bar maybe fed vertically to the cutter, andthe same end attained.

' claim as new, and desire to secure by LettersP-atentl 1. The rotarywheel or die I, in combinationA with the plunger or die'J,vibrating-cutter L, and box M, all arranged to operate in the mannersubstantially as and for the purpose specified.

2; The feed-tube Q, lined with a-suitable non-conducting material, andarranged to operate in connection with the cutter by means of spring-barS and cam F, substantially in the manner as and for the purpose setfol'lill. i i

i 3. The combination of the feed-tube R, box M, rcutter L, wheel I,plunger or die J, and discharging-ledges ff, all arranged for jointoperation substantially as and for the purpose specified.
